Answer:
8
Step-by-step explanation:
The question is on number of subsets
Number of subset is given by 2^n
n=3 in our question, A,B,C
2^n = 2^3 =8
They are; { }, A, B, C, AB, AC, BC, ABC
Answer:
The right answer is the first answer
Step-by-step explanation:
Look to the attached file
The top-left graph goes with the bottom-right equation, y=90(1/4)^x
The bottom-left graph goes with the top-right equation, y = 120(3/4)^x
The top-right graph goes with the bottom-left equation, y = 120(1/4)^x
The bottom-right graph goes with the top-left equation, y = 90(3/4)^x
y=90(1/4)^x has a larger percent decrease than y = 90(3/4)^x
cause if you multiply a number by 1/4, that's smaller than multiplying number by 3/4. so y=90(1/4)^x decreases really fast
same with the y = 120(3/4)^x ones
Answer:
a = 4/27 - b/54
Step-by-step explanation:
27a+1/2b=4
Subtract 1/2 b from each side
27a+1/2b - 1/2 b=4-1/2 b
27a = 4 - 1/2 b
Divide each side by 27
27a/27 = 4/27 - 1/2 b/27
a = 4/27 - b/54
Answer:
-2, -1, 0, 1, 2, 3, 4
Step-by-step explanation:
The number has to be smaller than 5 but greater than or equal to - 2
